I post it for those asking where to get her.
Those from USA, Canada, Central America, South America, Australia, New Zealand, United Kingdom, and Ireland can order her at Rightstuf. No pre-payment required.
Those living or residing in Japan till next year can order her at Aniplex+.
Those lucky enough to have a GSC partner shop in their area (mostly EU) can order her there.
The unlucky ones who have no options in the abovementioned categories are left with BiJ, NY, MBT and proxy orders. If you have an option for stores that offer her on a made-to-order basis, please, refrain from ordering her at BiJ and NY for the sake of the unlucky ones with no Aniplex retailers around.
Those who can't pre-order at Rightstuf or GSC partner shops and missed out on other shops that offered her to international customers can use forwarding service (e.g., BiJ or Tenso and the like) or a proxy of choice. There's a good guide if you don't know how forwarding order works. Also, the figure is made to order and unless Aniplex meets the limit earlier she can be pre-ordered till July 28.
Update! Those who missed out on her at BiJ and Nippon-Yasan and can't order at Rightstuf can still order her at Yokatta!
